Dekiru Activated Carbon Filter Precut for HPA300 Prefilter Compatible with Honeywell Air Purifier Filter Replacement, Fit for Easy Installation Advanced Filters (6 Pack)

This is a high density carbon that fits my Honeywell filter with minimum priming. The house is fresh smelling for weeks.

Great quality, carbon filters good for putting on the front of your air filter for your machine. They work very well. Highly recommend.

Used these to create custom filters for a 3D printer and to replace the filters on several air purifiers. They're easy to cut to size and can be layered for a thicker filter if needed. Completely eliminated the smell from the 3D printer.

Activated charcoal filters. Good for helping to eliminate odors. Can be placed in front of A.C. input to help eliminate sudden ( cooking, forget to take out the trash etc. ) odors. They are embedded with activated charcoal DON'T wash. You'll remove the charcoal.

The thickness is perfect to fit in my air cleaner. Very easy to cut down to fit in mine. No weird smells either. Good value for your money. I will buy these when needed again.

These go in my air filters and are very efficient. I will keep purchasing them.

I have a litter robot 4 and the replacement carbon filters are very expensive - $30 for six. I knew I could buy these sheets & cut enough to come out with quite a savings & sure enough I did. These sheets are a bit thinner albeit they are denser - Even if I end up doubling the filters I will still come out on quite the winning side. I haven't cut them all out, but based on the ones that I have cut out, I have more than doubled the quantity if I had bought the brand name filters. Based on the ones I have ready to go, it will be a year before I will need to purchase filters again - and I have three cats and empty the drawer bags twice a week so maybe that will help someone project how my use compares to theirs.

Exactly what my air purifier needed for an easy change out.
